The invention relates to a device to one end of which a syringe can be connected and to the other end of which the mouth or opening of a bottle containing a drug or medicine can be connected. The device comprises a closed chamber having enclosed therein a needle which is in connection with the syringe. Members are provided by means of which the mouth or opening of the bottle is steadily connected to the device and means enabling the needle to perforate a seal plug and then a small rubber plug mounted on the bottle only when the device is blocked onto the bottle so that in any case it cannot be disconnected therefrom. Such a device can be disconnected from the bottle only after the needle has been caused to reenter the closed chamber, so as to prevent any possible dripping of the liquid outside of the device.

A safety device for connection of a syringe to the mouth or opening of a bottle containing a drug or a small tube for drug delivery from the syringe, comprising an elongated inner body defining a cylindrical cavity, at one end of which a seat is formed for housing the free end of a syringe, an intermediate body having a hollow cylindrical extension which is housed and movable within the cavity of the inner body between a first end of stroke position defined by a retaining element limiting relative displacement of said inner body and said intermediate body in a first direction and a second end of stroke position defined by a retaining element limiting relative displacement of said inner body and said intermediate body in a second direction, opposite to the first direction, a shaped resilient plug sealingly closing the outward facing end of the cavity of said cylindrical extension, the other end of which opens into the cavity of the inner body, a housing seat for the mouth or opening of a bottle or a small tube formed at the free end of the intermediate body with said resilient plug projecting at the center of said seat, at least one flexible extension integral with said intermediate body and having a shaped portion thereof projecting to said housing seat for the bottle mouth or opening, an outer body superimposed to said intermediate and inner bodies, members restraining said outer body to the intermediate body enabling a mutual displacement between a position at which said extension is allowed to outwardly deflect, and a position at which the outer body interferes with said extension preventing the outward deflection thereof, elements restraining both said outer body and said intermediate body to the inner body, enabling the axial displacement of said outer body and said intermediate body relative to the inner body only when the outer body is located at the position at which it interferes with said extension preventing the outward deflection thereof, the cavities of said intermediate and inner bodies being adapted to house a hollow needle which can be connected to a syringe inserted in said seat of the inner body, the tip of said needle being positioned adjacent said resilient plug at the inoperative condition of the device and the top of said needle protruding through said resilient plug at the operative condition of the device.
